0918-0920 Biscuit Joiner & Sun Mao
Not a cooking class for biscuits, we continued with the next step of making a table: making cuts and then using biscuit joiner and glue to make our six-piece table top together.
This process reminds me of the joining skills of the traditional Chinese carpentry, 榫卯 (Sun Mao), which does not need glue, biscuit or nail to combine two separate pieces together (as shown below). This Sun Mao structure is one of the main structure that ancient carpenters use, which could not only maintain the furniture for hundreds of years but also show some artistic skills. At that time, the cost of building nails is more expensive, creative carpenters create these skills to join pieces together without any glue.
I am really amazed by carpenters’ understanding of the physical structures and forces and expertise skills. However, as times go by, the costs of building nails and using Sun Mao technique reverse, which lead to the situation that fewer people know this technique and use that in the industry. I hope as I grow more techniques in carpentry, I could have the chance to visit some traditional Chinese carpenters and learn more about this fading but intricate technique.
